By the early 26th century, androids were commonplace in Earth Empire society, but were viewed as an under-class. The androids finally became fed up with the situation and moved en masse to the relatively unused Orion System. They set up their own government, with the stipulation that humans living in the system could stay if they accepted android rule. The Earth Empire considered this a violation of sentient rights, and attacked, starting the Orion War. The Earth Military tried to use Cybermen against the androids, which eventually resulted in the Cyber-Wars. (AUDIO: Sword of Orion)

Although the term "android" was often used for robots of both genders, a female android was technically called a "gynoid", and they were referred to as such on occasion. (PROSE: Christmas on a Rational Planet)
